题目描述:
以上是朋友圈中一奇葩贴:“2月14情人节了,我决定造福大家。第2个赞和第14个赞的,我介绍你俩认识…………咱三吃饭…你俩请…”。现给出此贴下点赞的朋友名单,请你找出那两位要请客的倒霉蛋。
输入格式: 输入按照点赞的先后顺序给出不知道多少个点赞的人名,每个人名占一行,为不超过10个英文字母的非空单词,以回车结束。一个英文句点.标志输入的结束,这个符号不算在点赞名单里。
输出格式: 根据点赞情况在一行中输出结论:若存在第2个人A和第14个人B,则输出“A and B are inviting you to dinner…”;若只有A没有B,则输出“A is the only one for you…”;若连A都没有,则输出“Momo… No one is for you …”。
输入样例1: GaoXZh Magi Einst Quark LaoLao FatMouse ZhaShen fantacy latesum SenSen QuanQuan whatever whenever Potaty hahaha . 输出样例1: Magi and Potaty are inviting you to dinner… 输入样例2: LaoLao FatMouse whoever . 输出样例2: FatMouse is the only one for you… 输入样例3: LaoLao . 输出样例3: Momo… No one is for you …
解题思路: 真不戳,STL 真不戳 ~ 现在让我离开 STL 刷题的话,也许就举步维艰了。
通关代码:
#include <iostream>
#include <vector>
using namespace std;
int main() {
vector<string> people;
string val;
while (true) {
cin >> val;
if (val == ".") break;
people.push_back(val);
}
if (people.size() < 14) {
if (people.size() < 2) {
cout << "Momo... No one is for you ...";
} else {
cout << people[1] << " is the only one for you...";
}
} else {
cout << people[1] << " and " << people[13] << " are inviting you to dinner...";
}
return 0;
}
